The easiest way to use Binance Chain is through a wallet with support for Binance Chain accounts and transfers.

For example, Binance provides a Web Wallet at https://www.binance.org (https://testnet.binance.org for testnet), which provides the below functions:

Generating crypto keys and addresses, which serves as the base of a wallet

Showing the balances of assets on the addresses

Sending and receiving assets

Binance Chain Web Wallet also presents a trading UI similar to Binance.com, where you can examine market data and manage your orders to trade among the listed assets. Learn about the list of wallet available here.

Chain Explorer provides a portal to explore blocks and transaction details. On Binance Chain Explorer, you can also check different types assets, the distribution of their ownerships, and owners' transactions.

There are some data seed node in the network which allow users perform low-level operations like executing ABCI queries, viewing network/consensus state or broadcasting a transaction.
If you run a full node by yourself, you can also use those RPC functions. Here is a list of all the Node RPC services it provides: https://docs.binance.org/api-reference/node-rpc.html

SDKs are also provided as a starting point for your apps. There are two advanced sdk solutions for Binance chain: Java and Golang. Both solutions provide functions for:
Create wallets and manage keys
Encode/sign transactions and submit to Binance Chain/DEX, including Transfer, New Order, Cancel Order, etc.
* Communicate with Binance Chain/DEX Node RPC calls through public node RPC services or your own private full nodes
